What is oil-free scroll vacuum pump

Never scroll vacuum pump oil products in the late 1980s on the market until now, it has been nearly 20 years. While the research and development of this pump is much more than 20 years.

Scroll mechanism is Frenchman Creux patents in 1905. Was due to vortex institutions and other processing technology and equipment requirements, no processing equipment, high-precision machining center until the 1970s, before we implement this mechanism.

Movable scroll mechanism, fixed scroll scroll curve substantially the same, with respect to the movable scroll and the fixed scroll 180 ° apart on the eccentric to configure the installation, its contour lines around the crescent-shaped cavity, the movable scroll the crescent chamber moves toward the center of the plate movement and continuously and gradually decreases, and finally to a minimum at the center of the cavity, the internal gas to achieve high compression efficiency.

Based on the principle of the vortex generation mechanism. Scroll compressor comprising a scroll vacuum pump and the like.

Oil-free scroll vacuum pump is only one main moving parts of the orbiting scroll, and thus the power transmission is simple, compact, small machine size, fewer parts; intake and exhaust were synchronized and continuous unidirectional exhaust process is almost no gas pulsation, no aerodynamic noise, small changes in the driving torque, smooth operation, low vibration and mechanical noise, can greatly increase the speed (up to 36000r / min); moving between fixed and movable scroll scroll pump chamber the gap between the small, moving parts and cavities without friction, so almost no wear, low power consumption, energy saving; high reliability, high volumetric efficiency; no oil flow channel, to create clean, oil-free vacuum environment.

Because of this general oil rotary vane pump has incomparable advantages pump, but the orbiting scroll special shape, fabrication, assembly, high precision positioning requirements, and the process must be used machining centers, high cost, there are a lot of technical difficulty, so far its core technology lies in the hands of a world-class vacuum science and technology experts, only a few countries can meet quality requirements

In the alternative to ordinary rotary vane oil pump, the oil-free scroll vacuum pump with its no oil pumping process, low energy consumption, low noise, gas compression enables continuous torque and pressure fluctuations are small and easy to control, single stage can be divided into 3 ~ 4 cavity compression, the rapid development of such characteristics than large, become rough vacuum stage oil-free vacuum pump small mainstream products.

As each generation of new products and new technologies, like the history of the development of oil-free scroll vacuum pump products to emerge from now, still in continuous technological improvement and perfection of vigorous development process.

What is the vacuum
Vacuum means that a given gas pressure within the space of less than the area of a standard atmospheric pressure gas state.
Vacuum is rarefied gas environment. Compared with the atmosphere it has a number of advantages, such as gas thin, less oxygen, clean environment...

Vacuum pump in a variety of different job categories effect have?
Vacuum pumps work in a variety of different play areas in effect summed up in the following areas:
1, main pump: the so-called main pump is a vacuum system is evacuated container is directly evacuated to the vacuum pump ...
